LINFORD J". DAVIS, OF BATTLE CREEK, MICHIGAN.

SKIRT-GAGE. i

To all whom it may concern:

Be it known that I, LINFORD J. DAVIS, a citizen of the United States,residing at Bat tle Creek, Michigan, have invented certain new anduseful Improvements in Skirt- Gages, of which the following is aspecification.

This invention relates to improvements in skirt gages.

The main object of this invention is to provide an improved skirt gagewhich is very simple and economical in structure, and, at the same'time,satisfactory in use, and one which can be readily set up or knockeddown.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention, is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure 1 is a side elevation of my improved skirt gage. Fig. 2 is ahorizontal section taken on a line corresponding to line 2-2 of Fig. 1,the base not being shown. Fig. 8 is a horizontal section taken on a linecorresponding to line 33 of Fig. 1. Fig. 4 is a detail perspective ofthe base and of the standard, disassembled.

In the drawing, similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the base is preferably made up of two parts, 1and 2, having out-turned ends 3 forming diverging feet. These membersare formed of strips of sheet metal arranged back to back and secured bythe rivets 4. The member 2 is provided with a V-shaped offset 5 toprovide a socket for the standard 6. The standard is V-shaped or channelshaped in cross section, and is also formed of sheet metal. Its lowerend is slightly reduced at 7 to fit the socket and to provide shoulders8, which rest on the upper edge of the base member 1. The edges of thestandard are notched or serrated, at 9, the serrations being inalinement to receive the gage rod 10. A suitable scale is providedSpecification of Letters Patent.

for the standard, as shown. The gage rod 10 is formed of wire coiled toform a spring 11 at one end, one end of the spring being extended intothe standard-engaging arm or member 12. This engaging member 12 isV-shaped and is disposed across the rod 10 to embrace the rear side ofthe standard, clamping the gage rod in the notches 9. The end of themember 12 is formed into a loop 13, to receive the rod 10, whichprevents the twisting of the gage rod upon the standard, and the end ofthe loop also serves as a thumb piece. In adjusting the gage member, therod 10 is grasped in the fingers and the clamping members 12 pressedrearwardly by the thumb on the loop 13.

My improved skirt gage is very simple and economical in structure, andcan be readily adjusted and is eflicient for the purposes intended. Ihave illustrated and tie scribed the same in detail in the form in whichI have embodied the same for the market. I am aware, however, that it iscapable of considerable variations in structural details withoutdeparting from my invention, but as these modifications will be obviousto those skilled in the art to which this invention relates, I have notattempted to illustrate or describe such modifications herein.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A skirt gage comprising a sheet metal standard, V-shaped in crosssection; a base therefor formed of two sheet metal members havingdiverging feet portions at their ends, said members being arranged onedge and secured together back to back, one of the i:

members having a V-shaped ofiset therein to provide a socket for saldstandard, and a gage arm adjustably mounted on said standard.

2. In a skirt gage, the combination with a standard, of a base formed oftwo sheet metal members, each having an out-turned foot portion at leastat one end, said members being arranged and secured back to back byrivets arranged therethrough, one of the members having an offsettherein to provide a socket for said standard, there being a rivetat-each side of the ofi-set, and a gage arm adjustably mounted on saidstandard.

3. A skirt gage comprising a base, a standard V-shaped in cross section,and an ad ustable gage rod having a spring coil therein and a V-shapedextension for said coil adapted to receive said standard, the end ofsaid extension being provided With an engaging loop for said gage rod,the edges of said ed to receive said standard, the edges of saidstandard being serrated to provide gaging notches for said gage rod.

5. A skirt gage comprising a base; a standard; and an adjustable gagemember provided With a spring and a standard engaging extension for saidspring disposed across said gage member to engage the rear side of saidstandard and clamp said gage member thereto.

6. A skirt gage comprising a base; a standard; and an adjustable gagerod provided with a spring and a standard engaging extension for saidspring, said extension being disposed across said gage rod to engage therear side of said standard, the end of said extension being providedwith an engaging loop for said rod.

In Witness whereof, I have hereunto set my hand and seal in the presenceof two Witnesses.
